Honestly not trying to start a huge, worthless discussion about Police interaction but this is exactly why I tend to give the benefit of the doubt to cops in confrontations with civilians. No one ever walks into my office and opens fire on me at work while I'm updating client info or filing trade confirms. They have to always be ready to fight for their lives at a moment's notice... that's the definition of stress. I think this reality does take a toll on some officers and they use it as an excuse or justification for some of their actions... but shit, that's a tough way to live.
